Clary is very lonely at school and at home. One day she starts getting notes in her locker from someone who wants to be her friend, and maybe more. Will she ever find out who it is? And why does this person want to stay anonymous and doesn't approach her in person?

Clary is lusting after her hot math teacher, Mr. Herondale. She has tutoring with him every day after school. Is it just lust or is there more? Can Clary fight the temptation that is her teacher?
